SIGNALING ODOMETER.

Application filed March 20, 1925. Serial No. 16,913.

rlhe purpose ot this invention is to provide in and in connection with atravel indicating insti nuent mounted upon a vehicle tor registeringtravel by which the driver may be i adv ised of attentions required tromtime to time according to the mileage travel oi the vehicle by the motoror ruiming gear ot the vehicle, and being able to interpret saidadvices. lt consists in theL elements and features ot construction shownand described as indicated in the claims.

In the drawings Figure l is a front elevation ot a travel registeringinstrument constructed according to and equipped with parts oi'f thisinvention, shoivn mounted upon the instrut hoard oit a vehicle.

i. igure 2 is a side elevation ot the instrunient shoivn in Figure l,the instrument beh ho .vn in section.

. igiue 3 a perspective dissected view ot the dials of the mileageregistering train.

Figure 4.; is a detail section at the line l-Ll on Figure 2.

The draivinQ shoiv a customary form ot coniibined instrument comprisingspeedometer and odometer mechanisms and dials, the same being attachedby means ot a mountto the instrument board ot the vehicle to be served,The instrument casing is shoivn at fr. C is the mount. D is 'theinstrument board. The i: strument casing, A, is carried the mount iu theusual manner being ined through a central opening so that the at conLAttes a iange, being substantia y in the plane oi the face of theinstrument. rlie dials, 721, Z22, 703, b4 and 715, orE the total mileageregistering train, B, ot the acter, have eertoiv numeral areas dismarked'for .dicating the mileage at which attention is required by the ri gearor other parte. g, according to Well in diilerently coloreral areascorresponding ,s at which the ditterent atrequired "pectively Thus thehas at the numeral area vwhich l t the sight opening upon the coinineach 100 miles, green marl/ring as ted by the conventional hatching onf-a and The hundreds dial, b3, has e ialtern numeral area which willarrive at the sight opening upon the completion of any multiple ot 200miles travel*` colored blue, as indicated by the hatching in Figure 3,and this dial has also the numeral areas ivhich ivill arrive at thesight opening upon the completion ot' 500 miles distinguished by yellowmarkings, as indicated by the hatching in Figures l and 3, and it hasalso the area which ivill arrive at the sight opening upon thecompletion oi i000 miles distinqjuished by red markings, one-half otthis being red and the other half yelloiv, as may be understood from thehatching in 1Eigure l. rihe thousands dial, b4, has the numeral areaswhich ivill arrive at the sight opening upon the completion of each 5000miles distinguished by purple or broivn marking.

In order that the driver may interpret these distinguishing markingsupon the numeral dials in accordance With the Warning 'which they aredesigned'to give and the attention to the vehicle or any part thereoiEwhich is required at the mileage indicated, there is attached to theinstrument' an interpretiife chart, E, having imprinted prominentlythereon the several color-mark ings adjacent to the interpretationthereof, that is a textual statement of the attentions which arerequired upon the arrival at the sight opening oi the markingsrespectively upon the `dials indicating the mileage 'travel by reason etivhich the attention is required.

This chart is a relatively stitl metal plate or panel which is pivotallysuspended trom the instrument, the pivotal connection being mostconveniently made With the mount, C, at the flange portion thereof atthe under side ot the instrument Where pivotal lugs, C1, are provided,to which the upper end ol the panel, E, is attached. ln order that thepanel may be swung bach out ot display position, so as not toinconvenience the driver in the intervals between the Warnings which hedevice is intended to give, and by reason ot which the driver Willconsult the chart, and by reason ot the pivots heilig above the levelott the lower side of the casing, the upper end ot' the panel is cutaway or ref cessed between the points of its pivotal mounting as seen atel, thus accommodating the casing when the chart is swung back and upinto the position shown in Figure 2. For releasably retaining the chartin this position there is provided a spring catch, F, ivhicli is a fiatspring bar attached to the rear side of the casing and normally flexedto the forni shown in Figure 2, so that its free end is at a positionfor engaging the free end of the chart when the latter is swung back outof display position, as seen at said Figure 2. this free end or" thespring catch is formed with an engaging hook, El, into engagement withwhich the tree end of the chart will snap when the latter is swung backaga-inst said hook end; and when the driver cesires to consult the chartit is only necessary to reach under the instrument and push back thehook endo'f the catch, whereupon the chart will drop by gravity out ofengaging position and swing forward or be readily swung forward toposition for consultation. Y

I claim y l. A device for the purpose indicated coinprising incombination, a travel indicating instrument adapted 1Lo be mounted on avehicle and connected with the running gear thereof for registering thetravel of the vehicle, the distance-registering dials of said instrumenthaving the numeral areas denoting mileaqes at which different.attentions to the vehicle, its mechanism or parts,` are required,visuall7 distinguished by marks differentiated for aid ditferentattentions respectively, a permanent chart movably appended to theinstrument eXteriorly thereof, adapted to be t isposed at will in sightof the attendant in charge, containing substantial duplications of saiddifferentiated markings adjacent to definitions of said markingsrespectively. A

2. ln the construction defined in claim l, foregoing, the chart beingpivotally suspended from the lower forward side of the instrument andadapted to be folded back and up out of display position, and releas blemeans for holding it so folded.

ln the construction defined in claim l,r foregoing, the chart being arelatively metal panel having pivotal support at its casing. Y

el, in combination with the construction defined in claim 1a mountingmember for the same which, when the instrument isv mounted thereon,constitutes a flange projecting in a plane parallel to the face ot theinstrument, the pivots for the chart panel being carried by saidmounting member and projecting at the rear side of said flange, andlaterally disposed with respect to the instrument casin g, the upper endof the chart panel being recessed between the points 'of its pivotalconnection to accommodate its rearward and upward swing. away fromdisplay position.

5. A device for the purpose indicated, comprising in combination, atravel-indicating instrument adapted to be mounted on a vehicle andconnected with the running` gear thereof for registering the travel ofthe ve-V hicle, the distance-registering dials of said instrument havingthe numeral areas denoting mileages at which different attentions to thevehicle of its mechanisms or parts are required visually distinguishedby marks differentiated for said diflerent attentions respectively, amember for mounting said instrument on the vehicle from which theinstrument casing is separable, and a chart of permanent charactermovably appended to said mounting member' adapted to be disposed at willin sight of the attendant in charge, said chart containing substantialduplications of said differentiated markings and definitions of saidmarkings adjacent to the n respectively.

ln testimony whereof, I have hereunto set my hand at Chicago, Illinois,this 17th day of March, 1925.
